Hi,
  is there some known problem with error handling in floppy driver?
It complains loudly that "buffer layer error at fs/buffer.c:2641"
and fs/buffer.c:2690. It happened during floppy write. After reformatting
floppy write succeeded without any complaints.
                                            Thanks,
                                                   Petr Vandrovec
